SMALL-ARM.

To all whom itmag concern Be it known that I, PHILIP THOR/[AS Goo-- SAL,a subject of the King of Great Britain.

residing at Iscoyd Park, in Flintshire; near lVhitchurch, in the countyof Salop, Eng

land have invented new and useful Im- 'pro'vements in Small-Arms, ofwhich the A further object of the invention is to pro-' vide asimple andefficient form of safety catch.

In my former specification I have described an action in which thestriker and firing pin are'used, but for the purposes of the presentspecification the invention will be described in connection with adirect acting striker (as in previous actions of my invention anddesign) although the invention may be adapted to be used with myrotheractions. a Wheniising the rifle with sporting cartridges, giving a heavypressure it may be advisable to use a firing pin. f

According to this invention I form a striker of twopieces connectedtogether. by a screw; the fore" part extending backward from the pointto an enlargement or piston and the rear part consisting of a. stemscrewing into the piston and a cooking piece which latterextends aroundunder the-carrier and engages with a sear in the usual manner. A plugwhich acts both as an abutment for the rear end ofthe main spring and asa bearing for the stem is fitted in the bore of the carrier and extendsrearwardly beyond the carrier; The plug is of the same diameter as thebore of the carrier for the greater part of its length, but is ofgreater diameter at the rear end. At the front end of the plug is adiaphragm fitting the bore of the carrier and having a hole to receivethe stem of the striker and rearwardly from this diaphragm a passage iscut for the striker and the cooking piece to travel in, and near thefront end of the plug are-two lateral lugs. The bore of the carrier isof the same diameter throughout and along the bottom is cut a straightshallow groove ex- 1920., Serial No. 400,044.

tending the length of the bore and on the piston of the striker is adownwardly extending projection which fits into the groove and cantravel freely along it. The projection and groove prevent any tendencyto turn on the part of the fore part of the striker. A shallow groove iscut around the bore of the carrier near its rear end to receive thelateral lugs on the plug and to en- Specification of Letters Patent.Patent d O t 11 'IQZL Application filed July 30,

ablethese lugs to be inserted into this groove before they are turned alongitudinal groove is cut in the top of the bore as far forward as theabove mentioned groove and 0f the same size as the lugs for the upperlug to travelin.

As above mentioned the plug is of the same diameter as the bore of thecarrier except for a. lug at the rear end which is ap' proximately ofthe same diameter as, the outside of the cylinder ofzthe carrier and isrounded off at the rear end.

I insert a safety catch consisting of a broad ring having a radial thumbpiece into the space between the end of the carri er and the lug on theplug. The ring hasin it a gap through which the cocking piece can passwhen the radial thumb pieceis pressed down to the right in whichpositionthe rifle can be fired. r

If the thumb pieceis turned 180 to the .left the ring passes between thecooking holds the piece safe.. v Therear end of the ring is so. formedthat piece and the stem of the striker and so as it is turned it engagesthe inside ofthe bent part that joins the cockingpiece to the stem ofthe striker v and so draws it back sufiiciently to draw the cookin piecefrom out of engagement with the sear. Thus] as long as the thumb pieceis turned to the left the rifle cannot be fired. I 1

A spring plunger may be inserted inzthe thumb piece to take into smallrecesses in the plug and so to hold the safety catch in the open orclosed position.

My invention is illustrated by the accompanying drawing, Figure 1 ofwhichis a right hand view of an action showing the carrier in section;Fig. 2 is a right side view of the striker; Fig. 3 a rear view; and Fig.4 a front view thereof; Fig. 5 is a section on the line 55, Fig. 1;Fig.6 is a rear view of the carrier; Fig. 7 is a section of the plug;Fig. 8 is a front view thereof; Fig. 9 is a slde view of the safetycatch; Fig. 10

a part sectional rear view thereof; Fig. 11

is a front view showing the safety catch in the safe position; and Fig.12 is a view showing'it in the firing position. I

A is the carrier which is bored as shown to receive the striker whichconsists of two parts, the fore part B, the rear end of which isenlarged to form a piston B fitting in the bore of the carrier A, andthe rear part C, the front of which screws into the piston B while therear extends around under the carrier and forms a cocking piece C whichengages a'sear D. In the rear of the carrier A fits a plug E which isitself bored to allow the stem of the part C to pass through it. At thefront of the plug is a diaphragm E fitting the bore of the carrier. Nearthe frontof the plug are two lugs E which take into a groove A cutaround the bore of the carrier near its rear end and to enable the lugsto reach this groove a longitudinal groove A? is cut in the top of thebore from the rear end thereof as far forward as the groove A Betweenthe diaphragm E and the piston B lies amain spring F. rear of the plugis a lug E In order to prevent the possibility of the fore part Bturning a straight shallow groove A is cut along the bottom of the boreto receive a projection B on the piston B I r The safety catch consistsof a ring of steel G having in'it a gap. It is provided with a thumbpiece G This catch surrounds the plug just behind the rear of thecarrier. When the thumb piece is pressed down to the right and is in theosition shown in Fig. 12 the cocking piece 1 can pass through the gap inthe ring and the piece can be fired, but when the thumb piece is turnedin the other direction and lies'in the po sition shown in Fig. 11, thering G lies in the path of that part of C which unites the cooking pieceto the stem and therefore I the piece is safe.

, The ring G may be beveled off as seen at G so that when the catch isturned into the safe position this part bears against the cocking pieceand so draws the striker back sufficiently to remove the cooking piecefrom engagement with:the sear.

E E, are two recesses cut in the plug E and adapted to receive the endof .a spring plunger Gr carried by the thumb piece G At the by which thecatch is held in the required position,

To assemble the above parts, I first put the safety catch on the plug onwhich it is return (the screw in the piston allowing this to be done) sothat the lugs'E hold the plug in place. The cooking piece on-reachingthe passage cut for it snaps into its place. Thus the plug is locked inposition bythe cocking piece and cannot-be dismounted before the cockingpiece has been forced back clear of the carrier.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to-be performed, I declare thatwhat Iclaim is 1. In a block bolt action, the combination of a carrier,a striker formed in two parts screwed together and working in thecarrier and a detachable plug fitting. the rear of the carrier andlocked therein by the. striker.

2. In a block bolt action, the combination of a carrier, a strikerformed in two parts screwed together and, working in the carrier, adetachable plug fitting the rear of the carrier, a safety catchconsisting of a ring surrounding the plug and havinga "portion cutawayto allow the striker to move, and a thumb piece adapted to turn thecatcharound the plug. 1

3. In a block bolt action, the combination of a carrier, a strikerformed in. two parts a detachable plug fitting the rear of the carrierlocked therein by the striker, a safety catch consisting of a ringsurrounding the plug and having a portion cut away to allow the strikerto move, and a thumb piece adapted to turn the catch around the plug.
